The machine must be isolated from the compressed air network and completely vented before
undertaking any work on the pressure system.
Drain the oil completely from the following components:
■ oil separator tank
■ oil cooler
■ airend
■ internal heat recovery system (option W1/W2/W3)
➤ Always change the oil filter and oil separator cartridge when changing the oil.
➤ Contact KAESER Service representative if condensate is detected in the cooling oil. It is
necessary to adjust the airend discharge temperature to suit operating conditions.

machine itself or from an external source.
An external source of compressed air is necessary in the following cases:
■ The machine is not operational.
■ The machine is to be restarted after a long period of standstill.
